Research Projects by Subject

Note: Each research project will involve background reading for the interns provided by their mentors. Each research project will involve a final presentation by the interns.

Interns are expected to work collaboratively on the same project and/or data set. This may preclude rising seniors from submitting papers based on such projects to the Intel Science Talent Search competition.

ELE-01 Title: Electrical Characterization of Thin Films and Nanostructured Materials Using DC/AC Analysis
Primary mentor: Mingran Liu
Faculty advisor: Prof. Nobby Kobayashi
Other mentors: David Fryauf
Location: Other
Number of interns: 2

Project description: The mentor's research group, Nanostructured Energy Conversion Technology and Research (NECTAR), is developing novel and innovative thin films and nanostructured materials for several areas of competitive technology, including thermoelectrics, transparent conducting films, anti-reflective coatings, and chemical corrosion barriers. Design, fabrication, and characterization of such materials require many types of scientific tools, and precise measurements of electrical properties give us insights to the quality and potential applications of sample materials. This project includes both DC and AC electrical characterization and analysis of novel materials using four point probe measurements.

Tasks: The SIP interns should have some basic understanding of electricity (V=IR), but the interns will primarily be learning how to analyze and model various thin film and nanostructured samples based on their IV curves and impedance spectrum response. The interns will be working hands-on with the probe station and electrical analyzer components, and they will possibly be able to upgrade the system to include temperature-dependent or optically-excited measurements. This project will take place entirely in our off-campus lab located at 2300 Delaware Ave in Santa Cruz, but the SIP interns will have the option to work remotely when performing data analysis and creating their final presentation.

ELE-02 Title: Photoluminescence of One-Dimensional Materials
Primary mentor: Ravipa Losakul
Faculty advisor: Prof. Nobby Kobayashi
Location: Other
Number of interns: 2

Project description: Overview: One-dimensional materials, such as semiconductor nanowires, that are created by chemical vapor deposition process will be studied to assess the dependence of their photoluminescence properties (electromagnetic radiation) over a range of post deposition treatments (e.g., over-coating with dielectric materials). These materials are most commonly used for transistors, the fundemental hardware component in modern electrical circuits & devices. In a research environement, SIP interns will gain an understanding of the properties of semiconductors, chemical vapor deposition and post treatments. ——Key terms: (1) photoluminescence: light emission (in any form of matter – i.e., electrons) after the absorption of photons; (2) one-dimensional materials (a.k.a. nanowires): fabrication, properties (i.e., conductivity) and its applications; and (3) chemical vapor depostion process: how to create 1D materials.

Tasks: The SIP interns will be responsible for observing, recording, and analyzing the changes and results of one-dimensinal materials under various controlled post deposition treatments. Specfically, SIP Interns will: (1) understand the physics behind photoluminescence; (2) set up a photoluminescence measurement system; (3) perform measurements; and (4) analyze results. SIP interns may expect to ultilize simple software programs (MS Excel, LaTeX) to examine recorded data and document their findings into a lab report.
